width	double	false	null	width. If there is only [width] and no [height], you will get a dotted line in the horizontal direction.If there are both [width] and [height], you will get a dotted border.
strokeWidth	double	false	1.0	The thickness of the dotted line
dottedLength	double	false	5.0	The length of each small segment in the dotted line
space	double	false	3.0	The distance between each segment in the dotted line
corner	FDottedLineCorner	false	null	The corners of the dotted border. See [FDottedLineCorner] for details
child	Widget	false	null	If [child] is set, [FDottedLine] will serve as the dotted border of [child].At this time, [width] and [height] will no longer be valid.

📺 Demo

🔩 Horizontal Demo

FDottedLine(
  color: color,
  width: 160.0,
  strokeWidth: 2.0,
  dottedLength: 10.0,
  space: 2.0,
)

It is very simple to create a horizontal dotted line through FDottedLine.

The developer only needs to set the width parameter, but not the height parameter, which is all the developer needs to do for this.

If you want to control the thickness of the dotted line, set strokeWidth.

Through the dottedLength and space parameters, developers can freely control the length of each small segment in the dotted line and the distance between them.

⛓ Vertical Demo

FDottedLine(
  color: color,
  height: 160.0,
  strokeWidth: 2.0,
  dottedLength: 10.0,
  space: 2.0,
)

If you want to create a dotted line in the vertical direction, it is also very simple.

Developers only need to assign a value to height and leave width to be null or 0.

🔹 Dotted Shape Demo

FDottedLine(
  color: Colors.lightBlue[600],
  height: 100.0,
  width: 50,
  strokeWidth: 2.0,
  dottedLength: 10.0,
  space: 2.0,
)

FDottedLine can not only create simple dotted lines 🌝.

When developers assign values ​​to both width and height, they will be able to get a dotted rectangle! It's incredible.

🌏 Corner Demo

FDottedLine(
  color: Colors.lightBlue[600],
  height: 70.0,
  width: 70.0,
  strokeWidth: 2.0,
  dottedLength: 10.0,
  space: 2.0,
  
  /// Set corner
  corner: FDottedLineCorner.all(50),
)

With FDottedLine, developers can even create corner effects of dashed rectangles. For example: dotted rounded rectangle, dotted round...

🧩 Child Demo

FDottedLine(
  color: color,
  strokeWidth: 2.0,
  dottedLength: 8.0,
  space: 3.0,
  corner: FDottedLineCorner.all(6.0),
  
  /// add widget
  child: Container(
    color: Colors.blue[100],
    width: 130,
    height: 70,
    alignment: Alignment.center,
    child: Text("0873"),
  ),
)

In the past, it was very difficult to add a dotted border to a Widget.

Because the official did not provide us with a good solution. But now, FDottedLine makes things easier than ever. Developers only need to use their Widget as a child of FDottedLine.

/// #1
FDottedLine(
  color: color,
  strokeWidth: 2.0,
  dottedLength: 8.0,
  space: 3.0,
  corner: FDottedLineCorner.all(75.0),
  child: Container(
    width: 130,
    height: 130,
    alignment: Alignment.center,
    /// #2
    child: FDottedLine(
      color: color,
      strokeWidth: 2.0,
      dottedLength: 8.0,
      space: 3.0,
      corner: FDottedLineCorner.all(20.0),
      child: Container(
        width: 43.0,
        height: 43.0,
        color: Colors.grey[900],
      ),
    ),
  ),
)

This also means that through the nesting of FDottedLine, many super interesting views can be created.
